My A4 1.8T shuts off at idle or higher Rpms. My throttle plate seems to open up every time my engine is about to shut off. It helps to rev up the engine but eventually I will loose power. It acts as if it's miss firing but I did a tune up a few months ago. I think it could be my TPS, fuel pump, or CPS. Any clues?

 

is it when you are a higher rpms it like jerks around

 

It happens at iddle and higher rpms. Mostly when it idles.

 

I now know it's not my fuel pump. I have good fuel psi. I'm left with the cam position sensor or bad injectors.
